NAME

       bones-info - display information about a Nethack bones file

SYNOPSIS

       bones-info [-a | --auto] [-b | --big-endian] [--debug] [--help] [-x | --hexadecimal] [-l | --little-endian] [-v | --verbose] [--version]
       file...

DESCRIPTION

       bones-info displays information about a Nethack bones file.  By default it shows what byte sex it used to read the file and the 4 version
       numbers which constitute the feature set and platform for the Nethack binary which generated it.

ENDIANNESS (aka BYTE SEX)
       Normally bones-info reads the bones file in little endian order, regardless of the byte sex of the current system, mostly because it was
       originally written to help with diagnosing problems with hearse and that's the most useful behavior for that purpose.  You can use the
       --auto, --big-endian, and --little-endian switches to change this.

       --auto is particularly useful (and appropriate) when using --verbose.

OPTIONS

       -a, --auto
	   Try to guess the right byte sex (little endian or big endian) for each input file.  If there doesn't seem to be a right choice, bones-
	   info will output a warning, set a non-zero exit status, and move on to the next file.

       -b, --big-endian
	   Read the bones files in big endian order, such as is used by Macs.  See also "--auto".

       --debug
	   Turn debugging on.

       --help
	   Show the usage message and die.

       -x, --hexadecimal
	   Output numbers in hexadecimal form.

       -l, --little-endian
	   Read the bones files in little endian order, such as is used by Intel hardware.  This is the default, I include it so that you don't
	   have to check what the default is if you know you want it a certain way.

       -v, --verbose
	   Output more info about the bones file.  This tries to decode the 4 version numbers.	Its useful when you want to see what the
	   differences are between two sets of version numbers.  You'd normally want to use --auto when you use --verbose.

       --version
	   Show the version number and exit.

EXAMPLES

       Output the values as used by the hearse server:

	$ bones-info *
	bonD0.0     sex=l v1=1	      v2=2	    v3=3	  v4=4
	bonD0.4.gz  sex=l v1=50593792 v2=10357958   v3=555422078  v4=2759955912
	bonD0.8.Z   sex=l v1=1027     v2=3322682880 v3=2115050273 v4=3365241252
	bonD0.19    sex=l v1=50528512 v2=10357830   v3=555409789  v4=2558629316
	bonM0.1     sex=l v1=50593792 v2=404622406  v3=555417981  v4=2759955916
	bonM0.T     sex=l v1=50593792 v2=1969222    v3=555417981  v4=2759955912

       Output the real values as seen on the system which wrote the file (by guessing the byte sex of the file):

	$ bones-info --auto *
	bones-info: can't intuit byte sex of bonD0.0
	bonD0.4.gz  sex=l v1=50593792 v2=10357958   v3=555422078  v4=2759955912
	bonD0.8.Z   sex=b v1=50593792 v2=1969350    v3=555422078  v4=2759955912
	bonD0.19    sex=l v1=50528512 v2=10357830   v3=555409789  v4=2558629316
	bonM0.1     sex=l v1=50593792 v2=404622406  v3=555417981  v4=2759955916
	bonM0.T     sex=l v1=50593792 v2=1969222    v3=555417981  v4=2759955912
	zsh: exit 1	bones-info --auto *

       Decode the version numbers:

	$ bones-info --auto --verbose bonD0.4.gz bonD0.8.Z
	bonD0.4.gz: 18389 bytes
	       read as: little endian
	   incarnation: 50593792   (3.4.0.0)
	   feature_set: 10357958   (REINCARNATION SINKS KOPS MAIL TOURIST STEED
				    TEXTCOLOR INSURANCE ELBERETH EXP_ON_BOTL
				    TIMED_DELAY)
	  entity_count: 555422078  (33 artifacts, 433 objects, 382 monsters)
	  struct_sizes: 2759955912 (164 flag, 64 obj, 101 monst, 456 you)

	bonD0.8.Z: 22296 bytes
	       read as: big endian
	   incarnation: 50593792   (3.4.0.0)
	   feature_set: 1969350    (REINCARNATION SINKS KOPS MAIL TOURIST STEED
				    TEXTCOLOR INSURANCE ELBERETH EXP_ON_BOTL)
	  entity_count: 555422078  (33 artifacts, 433 objects, 382 monsters)
	  struct_sizes: 2759955912 (164 flag, 64 obj, 101 monst, 456 you)

	$ _

BUGS

       Unsigned longs are assumed to be 4 bytes.

       The --auto byte sex detection isn't robust.

       It'd be nice to be provide --verbose output for bones files from older versions.
